Problems solved by technology

[0003] In the related technology, the power source of the lifting platform comes from the oil cylinder. During the lifting process of the lifting platform, due to the different oil circuits of the two oil cylinders, there is a difference in the operating speed of the two oil cylinders, which in turn causes the lifting platform to tilt, causing the lifting platform to go up and down. The workpiece slips and falls, which is prone to safety accidents

Abstract

The invention provides a lifting assembly, a tunneling machine and a control method of the lifting assembly. The lifting assembly is used for the tunneling machine. The tunneling machine comprises a body. The lifting assembly comprises a platform, lifting ropes, multiple drive components, displacement sensors and a control device. The lifting ropes are connected with the platform. Any one in the multiple drive components comprises a cylinder body and a piston. The cylinder bodies are mounted on the body, the pistons can slide relative to the cylinder bodies, and the pistons drive the platformto ascend or descend through the lifting ropes. The displacement sensors are connected with the pistons and are used for detecting the stroke of the pistons. The control device is in communication with the displacement sensors and is used for controlling the running speed of the pistons according to the stroke of the pistons. According to the lifting assembly, the motion speed of each piston is controlled according to the stroke of each piston, then it is ensured that the stroke of each piston keeps consistent, the platform is prevented from inclining, then workpieces on the platform are prevented from sliding down, and safety of the construction process is ensured.

Description

technical field [0001] The invention relates to the technical field of tunnel boring machines, in particular to a lifting assembly, a tunnel boring machine and a control method for the lifting assembly. Background technique [0002] At present, in mountain tunnels and large-scale water diversion projects, the proportion of tunnel boring machines is increasing. When the surrounding rock is unstable, the tunnel needs to install anchor rods and vertical arch frames, and the required materials such as anchor rods, electric welding machines, steel bars, etc. need to be transported from the bottom of the tunnel boring machine to the upper plane of the tunnel boring machine connecting bridge with the lifting platform . [0003] In related technologies, the power source of the lifting platform comes from the oil cylinder. During the lifting process of the lifting platform, due to the different oil circuits of the two oil cylinders, there is a difference in the operating speed of th...
